9d764fc3c1 Do not generate '@' character in symbol names. 
MSP430 assembler does not like '@' character in symbol names, so we should
only use alphanumerics when we generate a new name.

5b093ebab2 Make names of types used in LLVM IR stable. 
Before this PR, type names could depend on the cratenum being used
for a given crate and also on the source location of closures.
Both are undesirable for incremental compilation where we cache
LLVM IR and don't want it to depend on formatting or in which
order crates are loaded.

e6aa92c432 trans: Make names of internal symbols independent of CGU translation order. 
Every codegen unit gets its own local counter for generating new symbol
names. This makes bitcode and object files reproducible at the binary
level even when incremental compilation is used.

rustc_trans: don't round up the DST prefix size to its alignment.

Fixes #35815 by using `ty::layout` and `min_size` to compute the size of the DST prefix.
`ty::layout::Struct::min_size` is not rounded up to alignment, which could be smaller for the DST field.

Address ICEs running w/ incremental compilation and building glium

Fixes for various ICEs I encountered trying to build glium with incremental compilation enabled. Building glium now works. Of the 4 ICEs, I have test cases for 3 of them -- I didn't isolate a test for the last commit and kind of want to go do other things -- most notably, figuring out why incremental isn't saving much *effort*.

But if it seems worthwhile and I can come back and try to narrow down the problem.

8fdc72f830 track MIR through the dep-graph 
Per the discussion on #34765, we make one `DepNode::Mir` variant and use
it to represent both the MIR tracking map as well as passes that operate
on MIR. We also track loads of cached MIR (which naturally comes from
metadata).

Note that the "HAIR" pass adds a read of TypeckItemBody because it uses
a myriad of tables that are not individually tracked.

9e706f90cb [LLVM-3.9] Configure PIE at the module level instead of compilation unit level

fba1f8f123 [LLVM-3.9] Setup the compile unit information immediately 
Since LLVM reversed the order of the debug info graphs, we need to have
a compile unit that exists *before* any functions (`DISubprogram`s) are
created. This allows the LLVM debug info builder to automatically link
the functions to the compile unit.

2f9fff2191 Keep multiple files per work-product 
In the older version, a `.o` and ` .bc` file were separate
work-products.  This newer version keeps, for each codegen-unit, a set
of files of different kinds. We assume that if any kinds are available
then all the kinds we need are available, since the precise set of
switches will depend on attributes and command-line switches.

Should probably test this: the effect of changing attributes in
particular might not be successfully tracked?

58d4b8edd3 Modify trans to skip generating .o files 
This checks the `previous_work_products` data from the dep-graph and
tries to simply copy a `.o` file if possible.  We also add new
work-products into the dep-graph, and create edges to/from the dep-node
for a work-product.
